But before he arrives at the White House, he will probably be forced to sign off. In addition to concerns about e-mail security, he faces the Presidential Records Act, which puts his correspondence in the official record and ultimately up for public review, and the threat of subpoenas. A decision has not been made on whether he could become the first e-mailing president, but aides said that seemed doubtful.

For all the perquisites and power afforded the president, the chief executive of the United States is essentially deprived by law and by culture of some of the very tools that other chief executives depend on to survive and to thrive. Mr. Obama, however, seems intent on pulling the office at least partly into the 21st century on that score; aides said he hopes to have a laptop computer on his desk in the Oval Office, making him the first American president to do so.

How crazy is it that the most important leader in the country can't use e-mail?
